Japan is widely considered one of the most technologically advanced countries in the world, and they plan to advance even further for the 2020 Games.

In a bid to promote de-carbonisation, all the electricity used at all the venues at the 2020 Olympic Games will be derived entirely from renewable energy sources.

Five thousand medals will also be made by recycling the small amounts of precious metals in old phones and cameras.

According to the Olympic website, the 2020 Olympic Games in Tokyo will be yet another example of Japan's ability to innovate technologically — it appears the organising committee for the Games is planning to fully power the games with renewable energy.

As reported by The Japan Times, all the electricity used at all the venues for the Games will be derived entirely from renewable energy sources to promote de-carbonisation.

Wind and solar sources will be used not only for the venues, but also for the athletes' village, the international broadcasting centre and the main press centre.

To draw solar energy, "solar roads" are expected to be set up. Essentially, these are roads lined with solar panels covered in resin so that cars will be able to drive on them without causing any damage.

Medals will also be made from recycling old gadgets like phones and digital cameras, with the small amounts of precious metals found in the devices estimated to create roughly five thousand medals.

A program to collect these devices that have been donated by the public has already been set up, with up to 14,636 metric tons of electronic devices recovered from the donation of roughly 80,000 phones and other devices so far.

Driverless taxis and robot translators are being introduced as well, to counter Japan's shortage of taxi drivers and any language issues for tourists.

Preparations for the Games are already underway, with most of the new changes expected to be completed in 2020 when the people from all around the world descend on the Land of the Rising Sun.
